One-component reaction coating

A one-component reaction coating is a special coating which, despite its one-part formulation, hardens through a chemical reaction. In contrast to conventional one-component paints, which mainly dry physically through the evaporation of solvents, reaction paints cure by reacting with environmental factors such as humidity, oxygen or UV radiation.

This type of coating contains reactive binders that undergo chemical cross-linking as a result of external influences, creating a particularly resistant and durable coating. Typical examples are moisture-reactive polyurethanes, which cure by absorbing moisture from the air, or UV-curing coatings, which polymerize under UV radiation.

Single-component reactive coatings combine the easy handling of a single-component system with the high performance of reactive coatings. They can be used in a wide range of applications, for example in wood preservation, for metals, in the automotive industry or for floor coatings.

The advantages lie in the ease of application, as no mixing is required, as well as in the excellent resistance to chemical, mechanical and environmental influences. Limitations may lie in the dependence on specific environmental conditions for curing, such as sufficient humidity or UV radiation. Overall, one-component reactive coatings offer an ideal solution for applications that require high efficiency and durability.
